Chinese culture seems to value education a lot more. It's a "face" thing I believe. My child did his first three years (grd 1,2,3) in a Taipei International School and when returned to the USA went to 5th grade instead of 4th. Other classmates moving to the USA and Canada also jumped a year but not all. It was on the strength of their math training which was lined up with the Chinese speaking elementaries in Taiwan. Based on this, I'd say at the elementary level, the Chinese elementaries are ahead. Also, my child was expected by the school to do homework every day. Chinese parents complain if there's no homework, even at that level.
